Embryo Implantation

Embryo implantation represents the remarkable synchronization between the development of the embryo and the differentiation of the endometrium. Implantation is the term applied to the process by which the blastocyst attaches to the wall of the uterus and begins to send fingers of tissue (chorionic villi) into the wall of the uterus as anchors. Blastocyst implantation and successful establishment of pregnancy require an appropriately prepared uterus and a dialogue between the blastocyst and the maternal uterine surface. A highly coordinated process is set into motion whereby specialized cells of the embryo, the trophectoderm and the throphoblast, establish contact with the specialized maternal tissue, the uterine endometrium. The blastocyst and endometrium generate a variety of factors that appear to be of functional significance during implantation.
